$userb = "$why4[1]";
$userc = "$why4[2]";
$userd = "$why4[3]";
if (strpos($brss[i], $usera) !== false)
// How can I
{echo "true";}
// ?
// I only get false
else {echo "false";}
}
如何通过用strpos询问特定单词来搜索数组，从而获得true？
如何echo "true";？
if (strpos($brss[**$i**],$usera)!==false) {
echo "true";
} else {
echo "false";
}
是的。
